Abstract (en)
[origin: WO2005014979A1] The invention relates to a run-in coating for gas turbines. The coating seals a radial gap between the gas turbine housing (11) and rotating impeller blades (10) of said turbine, said run-in coating (13) being applied to the housing. According to the invention, the run-in coating (13) is composed of an intermetallic titanium-aluminium material and can have a scaled or graduated material composition and/or porosity. Methods for producing said run-in coating include e.g. slip casting, physical vapour deposition (PVD) and chemical vapour deposition (CVD).
